Allegiant Air Baggage Policy Explained: Size, Weight & Fees

If you’re flying on Allegiant Air baggage policy before arriving at the airport can save you both time and money. Allegiant is a low-cost airline, which means your ticket typically includes only one small personal item everything else comes with an additional fee. This guide breaks down carry-on rules, checked baggage limits, and ways to avoid unnecessary charges.

Personal Item (Free Allowance)

Every passenger is allowed one personal item at no extra cost. This must fit completely under the seat in front of you.

Allowed size:

• Maximum dimensions: 16 x 15 x 7 inches (40 x 38 x 18 cm)

Common examples include:

• Small backpack

• Laptop bag

• Purse

• Compact tote

If your bag is larger than this size, airport staff may require you to pay for a carry-on at the gate which is usually the most expensive place to add baggage.

Carry-On Bag Rules

Allegiant does not include a carry-on bag in the base fare. You must purchase it separately during booking, online check-in, or at the airport.

Carry-on size limit:

• Maximum dimensions: 22 x 14 x 9 inches (56 x 36 x 23 cm) including wheels and handles

• Must fit in the overhead bin

  
  

Typical carry-on fees:

• During booking: cheapest option

• Before departure online: moderate price

• At airport counter: higher

• At gate: highest cost

Buying your carry-on early can save up to 50% compared to airport pricing.

Checked Baggage Policy

Passengers may check up to 4 bags per person. Checked baggage must follow both weight and size limits.

Weight limit:

• Up to 40 lbs (18 kg) per bag included in standard fee

• Overweight fees apply after 40 lbs

Size limit:

• Maximum combined dimensions: 80 linear inches (length + width + height)

  
  

Overweight & Oversize Fees

If your luggage exceeds the standard allowance, extra charges apply:

Bag Condition	Additional Fee
41–50 lbs	Overweight fee
51–70 lbs	Higher overweight fee
Over 80 linear inches	Oversize fee
Over 100 lbs	Not accepted

Because Allegiant’s weight allowance is lower than most airlines (many allow 50 lbs), travelers often get surprised at the airport. Weigh your bag at home to avoid last-minute repacking.

Sports Equipment & Special Items

Allegiant accepts special baggage but charges separate handling fees. Items include:

• Golf clubs

• Musical instruments

• Surfboards

• Ski and snowboard equipment

Some items may count as a checked bag, while others have flat special-item pricing. Fragile items should always be packed carefully because budget airlines offer limited liability coverage.

Smart Tips to Avoid Baggage Fees

1. Buy bags during booking – this is always the cheapest option

2. Measure your personal item carefully – Allegiant checks size frequently

3. Use a travel scale – their 40 lb limit is stricter than most airlines

4. Wear bulky clothing – jackets and hoodies don’t count as baggage

5. Share luggage – combining items into one checked bag often costs less than two carry-ons

6. 
   

Final Thoughts

Allegiant Air keeps ticket prices low by separating airfare from extras especially baggage. The airline only guarantees a free personal item, while carry-ons and checked bags require additional payment. By knowing the size limits (16×15×7 personal item, 22×14×9 carry-on, 40 lb checked bag), purchasing luggage early, and packing strategically, you can avoid surprise airport charges and keep your trip budget-friendly.
